LOUISPIERRE EMILE GENAT, OF PARIS, FRANCE.

. AUTOMATIC MACHINEFOR THE IflhNUFAGTUH/E 0F CAPSULES.

Application filed September 1'7, 19%.

To all whomit army cone-emit:

Be it known that 1, Louis Prnnnn Earths Gnzi vr, citizen oi. the French Republic, residing at Paris, Seine, in the French Republicpl'iave invented new and useful 1111- provenicnts in Automatic Machines for the Manufacture of Capsules, of which the following is a specification. i

The present invention has for its object an automatic machine which is intended chiefly for the automatic dosing and closing oi? capsules of the kind of pharmaceutical ones. Tlhis machine is characterized in that it coinprises three superposed plates separated by two thin discsor grids, theupper plate and the lower plateheing stationary; the interinedialoflplate being movable, and the two grids being connected together and movable, the inoven'ients of the intermediate plate, the grids, and the feed plate for the lower shellso't the capsule mounted on thenpper plate,bei1n controlled niecl'ianically or by hand by a single crank, the mechanical drive being also provided with ratchet devices intended to ensurethe absolutely fixed position of the movable pieces at the times when they are not to be moved. The machine is further characterized in that its plates carry several apparatus as follows: the hopper for feeding the powder, the shaking device, the two ejectors, the feed plate for the lower shells of the capsules, the two inclined guideways whereof one brings the lower shellsiand the other the upper shells by the upper plate, the compressing and dosing devices, andthe guides of the pistons controlling the ejector-s by the intermediate plate, and lastly the two closing; devices by the lower plate. I

Other features of the invention. will be clearly set forth in the following description. In the appended itlrawinp; which shows by way of example an embodiment of the in-- vcntion the plan views showing); the various parts in starting position:

Figs. 4? to 57 are diagrammatic views showing the operation of the device.

As shown in the drawing, the machine comprises a frame 1 which serves to support and contain the different parts of the machine. This frame carries the pins 2 which secure, by means of screw-nuts 3, the upper plate 4% of the ii'iachine. A lower plate 5 is secured below the plate if by two pins Between these two stationary plates l and .is an intermediate movable plate 6 secured to the shaft 7, by means of the square fitting 8. This shaft controls the movements of said intermediate plate which has suitable perforations 132 to afford passage to the two pins 133 which connect together the plates 4- and (See Figs. 5-4;),

Between the plates i and 6 is a grid or plate of small thickness 9 (Fig. 33) and between the plates 5 and 6 a grid 10 (Fig. 34). These two grids are connected together by the rings 11, 12, 13 and the pins 1-4: which join the same. These rings also serve for centering the grids and guiding the travel of the capsule-shells as will be stated below.

The lower grid 10, (Fig. 5), has a large cut-out part 15 in which is p aced a piece of sheet metal 16 of the same thickness as the grid and centered by the shaft 7. The motion of this piece 16 is controlled, by contact with the ejector control rods mounted on the movable intermediate plate as later described. A disc 17 is slidahly mounted on the shaft 7. An arm 18 secured to the machine frame passes through a hole 19 to prevent said disc 17 from turning (Fig. 18).

The intermediate plate 6 and the grids have an alternate rotation about the shaft 7 whilst the disc 17 has an alternate straight motion along the same shaft, by means of the following mechanism; the crank 20 (Fig. l) mounted on the shaft 21 (Fig. 3) actuates the shaft 24 by means of a worm or other gears 22 and 23. The ratio of said gears may for example be so chosen that one turn of the shaft Ql corresponds to two turns of the crank.

n the shaft 2t is mounted a plate 25, (Figs. 3 and 13). A roller 26 is pivoted on the lower face of said plate and two rollers are pivoted on its upper face. On a shaft 28 parallel with the shaft 24- are mounted. two discs 29 and 30 having grooves 31 and 32 in which engage the rollers 24% and 527. The disc 30 is fastened by means of pins to the shaft 28 and the disc 9.9

loose on this shaft. The disc is secured by a sleeve to a gear wheel 3% engaging a co-operating pinion 85, (Fig. 14-) nounted on the shaft 36 parallel with said shafts 24- and 28. This shaft carries a crank 37, (Fig. 16), which controls by means of a link a crank 39 secured to the shaft 7 to which is fitted, as above mentioned, the intermediate plate 6. The number of grooves provided in the disc and the ratio of the gears 34, 35 should be such that the frequency of the alternate motion of the plate 6 is adequate with reference to the other movements of the machine. One may for example use a disc having six grooves, and thus per turn of the shaft 2 L the sleeve 33 makes turn. If the pinion 3 has teeth and if the pinion has 18 teeth, the shaft 36 will make turns e" turn of the sleeve 33 or the shaft 36 will make %ft or turn per turn of the shaft 24. The rerative lengths of the crank arms 37' and 39 connected together by the link 38 is such that per turnof the shaft 36, the intermediate plateiraaltes gturn. Consequently, said intermediate plate will.
